DefaultResourceCalculator ClassNotFoundException
Hi all

  It‘s wierd to failed to start my yarn resourcemanager with an
exception[1].

    I aslo do some google, someone also encountered this problem with no
solved answer.
    I check the src ,there is actually no the DefaultResourceCalculator in
package :org.apache.hadoop.yarn.server.resourcemanager.resource,however I
found the DefaultResourceCalculator  in org.apache.hadoop.yarn.util.resource

    why we miss the class?
